Frequently Asked Questions

The 34-13SA kit converts a Holley 4160 series carburettor (which uses a fixed secondary metering plate) into a 4150-style secondary circuit. This allows engine tuners to install standard screw-in Holley main jets in the secondary fuel bowl for precise air/fuel ratio tuning.

This kit is specifically tailored for 4160 vacuum secondary carburettors with side-hung fuel bowls and shiny aluminum finishes, such as the 0-3310SA and 0-80508SA 750 CFM models.

No, this secondary metering block has no provision for a power valve. It is engineered for secondary vacuum operation where enrichment is regulated purely via secondary main jet sizing.
